Most of these medications are commonly used in the emergency department, and interaction between these medications increases the risk of this iatrogenic complication. We describe a patient on methadone therapy who developed TdP after she received metoclopramide and metronidazole. Interaction between different classes of medications can increase the risk of QTc prolongation and TdP. Awareness of this condition and its risk factors need continuous reinforcement among all hospital personnel to reduce the risk of this life-threatening complication.<\/jats:p>","DOI":"10.3390\/clinpract11010015","type":"journal-article","created":{"date-parts":[[2021,2,8]],"date-time":"2021-02-08T20:51:51Z","timestamp":1612817511000},"page":"101-105","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Methadone, Metoclopramide and Metronidazole Interaction Causing Torsades de Pointes"],"prefix":"10.3390","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0463-5225","authenticated-orcid":false,"given":"Karthik","family":"Gnanapandithan","sequence":"first","affiliation":[{"name":"Department of Internal Medicine, Mayo Clinic, 3500 San Pablo Road S, Jacksonville, FL 32224, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nishrutha","family":"Karthik","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine, Yale University School of Medicine, New Haven, CT 06510, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jaime","family":"Gerber","sequence":"additional","affiliation":[{"name":"Department of Cardiology, Yale University School of Medicine, New Haven, CT 06510, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2021,2,7]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1013","DOI":"10.1056\/NEJMra032426","article-title":"Drug-Induced Prolongation of the QT Interval","volume":"350","author":"Roden","year":"2004","journal-title":"N.
